Oblivion:Disease

Contracting a disease weakens specific skills or attributes of your character. Disease effects will remain active until cured with a potion, spell, or an altar or wayshrine. With few exceptions, diseases drain your attributes and should be cured as soon as possible. One particularly notable and somewhat unique disease is Porphyric Hemophilia, which will turn your character into a vampire three days after contracting it. Multiple disease effects will stack together. Although beggars carry diseases, they will only infect the player when attacked. This is rare however, given that all beggars have low aggression and therefore tend to flee instead of fight. Also note that diseases cannot be spread by the player.

The following table lists each disease, its symptoms, and the creatures or beggars that spread it.

Characters with Resist Disease abilities are less likely to be infected.

Astral Vapors ignores disease resistance. Therefore, characters with 100% Resist Disease and 100% Resist Magic (eliminating the possibility that a Weakness to Disease effect could be added) can still be infected with Astral Vapors.
